If so I suggest you forget adding internet connections to a dated TV since it was only the beginning of that effort. For the same dollars you should be able to get a current, more capable internet system and WiFi with a newer BluRay player.
I have a Samsung TV Model 46B8000XF. The instruction manual recommends that I use a Samsung Wireless adapter WIS09ABGN. However, I have purchased adapter WIS12ABGNX. Can this work with my TV?
